Abstract
A modified scaffold support post includes areas of reduced diameter, intermediate the length of the support post, having connecting rosettes secured to these reduced diameter areas. Preferably the areas of reduced diameter correspond to diameter of support tubes used as uprights in scaffold frames in North America (approximately 1.69 inches in outer diameter). Preferably the areas of reduced diameter are formed by swaging a tube of a larger diameter, typically approximately 1.90 inches. The modified support post is advantageously used with scaffold frames with connecting rosettes appropriately positioned on the uprights of the scaffold frames.
Claims20
A scaffold support post comprising an elongate support tube of a predetermined length and of a first diameter;
- said elongate tube having a series of securing rosettes at spaced positions in a length of said elongate support tube with at least one securing rosette intermediate the length of said elongate support tube;
- said elongate support tube including adjacent said at least one intermediate securing rosette an inwardly recessed swaged segment having an outer wall portion generally parallel to and positioned inwardly of an inner wall of said elongate support tube in a non swaged region of said first diameter, said swaged segment being sized to receive and engage a ledger head both above and below the respective intermediate rosette at various securing positions around the rosette.
An integrated scaffolding system comprising scaffold support posts, scaffold frames, and connecting ledgers and diagonal braces for securing said scaffold posts and said scaffold frames in predetermined modular spacing that allows scaffold posts to be substituted for scaffold frames while maintaining the same modular spacing;
- and wherein each scaffold support post comprising an elongate support tube with a series of securing rosettes at spaced positions in a length of said elongate support tube including at least one securing rosette intermediate the length of said elongate support tube;
- said elongate support tube being of a first diameter and including adjacent each intermediate securing rosette an inwardly recessed swaged segment of reduced diameter having portions generally parallel to and positioned inwardly of said first diameter sized to receive and engage a ledger head both above and below the respective intermediate rosette at various securing positions around the rosette.
